Interesting... I can understand what you mean by a "dead initializer", but I'm not sure what you mean by "wrapping" a dead initializer.
If the block was to set multiple variables that needed to be initialized, would you do:
```rb
var_a, var_b, var_c = nil, nil, nil; some_method do
  var_a = this
  var_b = that
  var_c = them
end
```
I think this is more readable:
```rb
var_a, var_b, var_c = nil, nil, nil
some_method do
  var_a = this
  var_b = that
  var_c = them
end
```
But as you say, it's a matter of preference.
To be clear, I'm in no way criticizing, I'm just curious :)
